lubasha [3.4K]

Answer:

Jesse is risking blood pressure by taking methamphetamines.  

Explanation:

Methamphetamine is a drug which effects the central nervous system. It gives brain a constant rush of dopamine. But abusing It puts the user to a number of side effects such as high blood pressure, fast breathing, and rapid heartbeat.

Methamphetamine can be usually consumed through a number of ways such as smoking, taking a pill, snorting, using injections in which the powder has been dissolved in alcohol or water.

Baldness (B) is inherited as X-linked dominant disease. An affected male marries a homozygous recessive female. What is the prob
torisob [31]
This can be solved with Punnett squares. The affected male has the X^{B} y genotype, and the female is homozygous recessive. This means that she does not carry this, and therefore, will have the genotype XᵇXᵇ

While doing this Punnett Square, keep in mind that in order to have the male offspring affected, their genotype has to be X^{B} y

Since there are no X^{B} y, the probability of their male offspring inheriting this disease is 0%

What is the difference between the null and alternative hypotheses? Give an example of each. How would you support or fail to su
Gekata [30.6K]

Answer:

Null Hypothesis:

The null hypothesis reflects that there will be no observed effect in our experiment. In a mathematical formulation of the null hypothesis, there will typically be an equal sign. This hypothesis is denoted by H0.

The null hypothesis is what we attempt to find evidence against in our hypothesis test. We hope to obtain a small enough p-value that it is lower than our level of significance alpha and we are justified in rejecting the null hypothesis. If our p-value is greater than alpha, then we fail to reject the null hypothesis.

If the null hypothesis is not rejected, then we must be careful to say what this means. The thinking on this is similar to a legal verdict. Just because a person has been declared "not guilty", it does not mean that he is innocent. In the same way, just because we failed to reject a null hypothesis it does not mean that the statement is true.

For example, we may want to investigate the claim that despite what convention has told us, the mean adult body temperature is not the accepted value of 98.6 degrees Fahrenheit. The null hypothesis for an experiment to investigate this is “The mean adult body temperature for healthy individuals is 98.6 degrees Fahrenheit.” If we fail to reject the null hypothesis, then our working hypothesis remains that the average adult who is healthy has a temperature of 98.6 degrees. We do not prove that this is true.

If we are studying a new treatment, the null hypothesis is that our treatment will not change our subjects in any meaningful way. In other words, the treatment will not produce any effect in our subjects.

Alternative Hypothesis:

The alternative or experimental hypothesis reflects that there will be an observed effect for our experiment. In a mathematical formulation of the alternative hypothesis, there will typically be an inequality, or not equal to symbol. This hypothesis is denoted by either Ha or by H1.

The alternative hypothesis is what we are attempting to demonstrate in an indirect way by the use of our hypothesis test. If the null hypothesis is rejected, then we accept the alternative hypothesis. If the null hypothesis is not rejected, then we do not accept the alternative hypothesis. Going back to the above example of mean human body temperature, the alternative hypothesis is “The average adult human body temperature is not 98.6 degrees Fahrenheit.”

If we are studying a new treatment, then the alternative hypothesis is that our treatment does, in fact, change our subjects in a meaningful and measurable way.

Hope this helps!

What adaptation allows the Artic fox to survive in its environment?
Hunter-Best [27]

Answer: Arctic foxes have several adaptations that allow them to survive. Their round, compact bodies minimize surface area that is exposed to the cold air. Their muzzle, ears, and legs are short, which also conserves heat.
